SILO.

1,032,765, specification of Leiters raient.

To allerhom may concern.

BeA it known that l, AnoLPr-r C. OC-ns, a citizen of the United States.7 residing fat Springfield. in the countyof Brown and State of lliinnesotaj hare. invented certain new and useful lmprorements in Silos, of

which the following is a specification.

lrlyinvention relates to silos and especially to silos constructed of hollow burnt clay blocks such as that illustrated and described in my application for Letters Patent, Serial Number (323,467, tiled April 26, 1911.

It is the object ofy my invention to provide such silo with a continuous door open ing, and to so construct the silo and the said door opening as not to weaken in any way the reinforcement of the walls of the silo against spreading strain causedv by pressure of the contents of the silo, and at the saine time to stiffen thedoor post structure as to enable the silotowithstand external wind pressure withoutf'yibratins which. mightl result in cracking of the walls thereof. To this end," at the sides of the'door opening which interrupts the wall of thel silo, said wall beingcoi'istructed of hollow burnt clay blocks so arranged as to form continuous CircumferentialA airV spaces in the body of the'iwall, a .series of straight hollow blocks arearranged one above the other with the openl ends eontactingso as to form continuons'ehannels extending vertically at each side of said door opening, reinforcing rods are arranged in the channels to which the reinforcing members of the silo are secured, and the yertical channels are then filled with concrete forming with said post blocks and rods united vmonolithic door post columns of a comparatively massive', and heayy type, y'

,Further objectsand advantages of my inf z; vent-ion will appear in connection' with the detailed description thereof and are particularly pointed out in they claims.

Upon a foundation 10 of any 'desired material the walls of my silo are formed in the manner described in the aforesaid applica'.- tion by means of hollow burntY clay blocks 11. A door opening 12, as indicated in Figs. 1 and 8, is provided extending from aty or close to the foundation to the top of the silo. The posts or jambs of said door opening are formed of hollow burnt clay blocks 13 set into the wall so that the openings lll therein will extend vertically. Some of the aforesaid blocks, as thus shown at 157 will preferably be formed longer than the blocks 13 so that the wall structure formed by these blocks will interlock in the desired manner, as shown more particularly in Fig. 2. In forming these longer blocks 15 it may be desirable to provide an additional passage 1G therein, although it is practicable and falls within the scope of my invention to have but a single passage 14 through each of said blocks. It will be understood that in the silo. structure proper, as described in the aforesaid application. the hollow burnt clay blocks used to forni the walls ofthe silo are f constructed of flat-sided burnt clay blocksk curved in oliv-direction and formed with openings extending through the blocks in the arel of curvature, said blocks being.r laid with the fiat-sides contiguous so that the openings therein will provide circumferential air spaces extending from one side of said door opening to the other, indicated at 17in Fig. 2. The passagethrough the bloelis 13 used in the door post structure therefore would. after said blocks 13 are all placed in position, form a vertical passage 18 extending;` at right angles to the horizontal passages in the body of thel wall.

Set within the foundation 10, 'as indicated atl 19 in Figs. l and 8, are vertical reinforcing rods 2O of. steel or other desired material and of such size and weight as the requirements of the particular structure may demand. The reinforcing. rods 20 extend upwardly through the center of the passage 18 formed by the openings 14 in the door post blocks 13. As the silo is raised duringr the Construction thereof the passage 1S is filled with concrete, thus securing together the blocks 13 and 15 and the reinforcing ture comprising the jamb 'ci post om-y continuous silo door. leinorcing members '21, preferably formed ol twisted wire, extend circumferentially wit-hin the body of the wall between courses ot' the hollow burnt clay blocks forming said wall. as described rod 2O to form a unitary 'menolirmc struc-,v E,

and claimed in my .application aforesaid..

The reinforcing members 21 are secured at their ends'about the rods 20, as indicated at 22, during the construction of the silo. rIhe circumferential reinforcement- 'of silo is therefore directly secured to the rods 20 forming a part of the posts of said continuous doorway.

To make etlective' the circumferential re-4 inforcement of the silo and prevent spreading of said walls either at the posts o'r elsewhere, I-have provided means extending across the door opening 12 for tying said posts together in nonspreading relatiomv In the preferred form shown'A invFigs. 1 to 5, I use tie-rods 23 which may be simply bars of iron having the'ends thereof bent at right angles, as shown at 24: in Fig. 3, or the ends may be bent in hook-like form, as shown at 25. In either case the bars 23 will be laid between courses of the blocks 13 and 15, the angled portions 24; or 25 o-said bars;

extending overl the vertical bars 20, so" that when the concrete is :poured intothe chan-` nel 18 formed by the openings 14:' in the blocks 13 and 15 the cross bars 23 will be rigidly secured to said posts. Where a more powerful cross reinforcement is -'desired the means shown specifically in Figs. 6 and 7` may be employed, which comprise flange plates 26 extending across the opening, asA

indicated in Fig. 6, said ange plates having holes in the ends thereof through which the bars 2O pass, the flanges being cut away at 27 where the. bottom plate 2S enters the wall structure. After the cement has `been poured the members 26 will be rigidly held within and practically integral with the door posts, forming an extremely powerful and eflicient construction. 4

Thel permanent cross reinforcing members, whether those indicated at 23 or the flange members 26, will be spaced sutliciently far apart to leave a convenient distance between pairs of said members for. permitting entry within the silo and the 'discharge of its contents therefrom. This distance will be too great to permit such membersto be used as a ladder-way. I have Vtherefore invented removable reinforcing -membcrs to be introduced in the continuous doorway between said permanent members whereby said permanent members in connection with said removable ,members will form a ladderway for entrance to any level in the silo. To etl'ect this arrangement I provide short eyebars which may be bent rods, as shown at 29, orplates, as shown at 30, said eye-bars be- -into positie -and plumbedfas the silo wall is l l .face adapted to coperate .viths cession with the utmost ease emptied.

Each .of the' bloclrlfand l5 with. one edge thcreot beveled shown at 34, and these blocks .are posi.

w is structed so that the beveled poL a of will form a contimiousbes` faces formed Lon the sides. of the noon used with my s1lo. AThese doors, which are best shown 1n F 1g. 3,-' may be named of two ormore -layers of wood or other material,

as desired, said vlayers being offset at the Aends thereof, as indicated at fixen the silo is being illed each door is successively placed in position one above the other, as shown, the pressure of the ensilng'e within the silo operating to vforce the beveled surfaces of the door against the correspondingly beveled jamb surfaces 34 'of the door osts and also holding*- 'the overlapping Jpints 35 between' the doors so that the same will be tightly secured, said pressure operating not only to" hold the' doors in position but also to seal said 'joints in a. practically air-tight manner. Owing to the nature of the joint formed between the individual sections of the door and between the door and ythe jamb surfaces of the door :frame thesections of the door .may be remoefl .insuc- A thel silo is I claim: x
